December My invention relates to separators and has to do more particularly ywith the provision of a rotary spraying separator for the separation of fluids and solids, and is particularly f5 useful in connection withv paints such as wall paper paints, although not 'confined thereto. n In the manufacture of paints for making wall paper, and for that matter also in other kinds of paints, the various ingredients that i0" go into the' manufacture of the same are not always dissolved and it is desirable to .elimie nate, lremove or strain such solids from the fluids. t l

' One of the objects vof my invention is to 1'5" provide a rotary sprayingvseparator of the character described which is simple in con-k struction, comparativelycheap to manufacture, easy to maintain and clean, and positive in its operation. There are various feaf'f'g tures and advantages which will be pointed out herein or will be apparent from an understanding` of the machine. For a better' understandingof my invention vreference is to be had to the accompanying1 drawings, in whichi i ig.` 1 is a side elevation partly in section; Fig. 2 is a top plan view of Fig. 1; and Fig. 3 is a top view of the 'rotary sprayer head along the lineB-B of F ig. 1. f

'ad' Referring first in general tothe operationV of the machine, the paint is `fed to the machine vthrough a pipe or feed chute so that it runs down into the upper feeding funnel ,I and into'the rotating spraying pans carried at Vthe lower end of the motor shaft. The paint feeds down into the pans and is thrown outwardly by lcentrifugal force against a separator or strain-ing screen. Some of the fluidv l of this sprayed paint is forced through 'the '47o screen and the solids and some of the fluid runs downwardly into the lower pan, which after it fills up comes in contact with the surface of the spraying cone at the bottom of the shaft which acts also as a centrifugal pump, gradually working upwardly to be again thrown against the screen to be strained, this operation continuing ina cycle until the lower pan is filled with solids, when it is removed and cleaned. Referring nowmore in detail to the pre- 3, 1925. serial No.raesa.

Vwardly and supports the spraying mechanismV which includes a plurality of spraying` discs preferabl f bowlshaped elements 12 se-` cured together y bolts 13 which pass through the rims of the pans and through separating sleeves 14. I preferably employ the bowl shape as this gives 'greater friction to the material than if a flat disc were used, and thus greater force to the sprayed material.l (All pans above'the lower one are vopen at the bottom at 12 so that the paint 4will feed on downwardly through the multiple bank of pans.

The lower pan 122 is preferably continuous, that is without an opening in the bottom, and carries a hub 15 for securing the spraying device to the shaft 11. I have shown three pans, but it is to be understood that the number of pans mayi be varied to meet'the conditions of use and the output desired. That is, by using a greater number of pans a greater output may be secured. Y

Beneath the lowermost pan I attach a com-v bination pump and sprayingcone 16 prefer. ably open at the bottom and extending downwardly so that the overflow or surplus paint going into the bottom pan 29 will come in contact'with this cone; By reasonv of the shape of the cone and its rotary motion this surpluspaint is again drawn upwardly to) be sprayed against the straining screen.

Thusthe spraying and pumping actions areV continuous so vlong as any .fluid matter remains to be strained. 1 y y Above the spraying pans I provide a cornT bined cover and feeding pan 17 heldin an outer rim 18, which rim rests inthe casing 25 so that this pan maybe lifted upwardly for access to the interior of the machine.` In,

order to hold the panclear of the interior I provide yielding holding elementsV in the" form of flat springs 19 secured to the arms .9

of the frame, so that the rim 18 may be forced up over .theV1 springs 19`jand held theref To i drop the feeding'paiil a spring 19 is pushed ...outwardly to release the pan so that it may be lowered intoy feeding position. f

The paint may befed to thispan 17 any suitable way'aiid I have'sliown a Vfeed pipe Y 20 with it's'nozzle [positioned 'above the pan i andv which pipe maybe so arranged that it M Vcan beturned to one side. to allow thefeedling p`anll7to-be.raised. Y

ln order to prevent Van overiiow of paint fion'r thelower pan`29 up'fto the screen 21,

should too much paint be fed to'tl'ieinachine, and to indicate to the operatorwlien too Y' much .paiiitfis being fed tothe ina'cliine,"`1 provide anoverflow pipe '34 Vwith its opening` .the spraying and pumpinglhead including the pans 12and cone 16. Thejpaintis now y.

lping into thefupper pan 12 :is-thrown or sprayed against the screen 21, the surplus paint in the upperpan 12 .flowing downwardlykthrougli its central opening 12y and beingtlirowii outwardly against-.the second pan 12 where by centrifugal force it is thrown outwardly aainst -tlie screen. In this secondror intermediate pan the surplus paint .flows downwardly through the central opening andv intothe `lower. panv 122. From thisV lower panit is likewise thrownl outwardly against the screen 21. By'this centi'ifugal `spraying action' thevfluid of the paint is forced through thejs'croen21 and `either flows down the outer faceof the screen 21, or some of the fluid may be forced through suiciently to drop down through Athe space inside the protective covering 25. and into the vreceiving; annular pan 26.` It lwill thus be seen that as this paint is sprayed outwardly against 'the screen 21 a part of the fluid is forced through the screenbutf the solids in the paintviun down along-the inner wallof 1 the screen 21 carrying part of the fluidv with it, for example suchas isfnot forced through the screen and whichthe .screen cannot take Careof. So. we have the inner face .of this screen ,carrying the "downwardflow of solids and-iadhering1 fluid.

.. Itis to be noted tht t thespiayiiigrporti on offfthe head is distributed so as to'sprayithe paint substantially along the entire screen and a desired number of spraying elements and c orres'pondinglength of screen maybe used,t depending upon the 'output desired. Y

As the paint isthrown or sprayed from the. i

revolving spray Ahead it travels with a for-` Ward or tangential motion due to the centrifugal for`ce,*and upondmpact with the emesse screenthat portion of the paint not going through continues its forwardmotion running down on the inside of the screen in a y29. This pan 29 gradually ills up, with the Y heavier particles sinking to the bottom and Vthe iuid matter floating to the topruntil it comes into Contact with the open bottom cone pumpingelement 16. The paint is then in effect uniped upwardly by action of the revolving cone, that paint which is drawn up alonetheouter face of the cone being thrown outwardly along its surface against the screen, while a greater amountis carried up along the inner face of the cone until `it reaches the top where it is thrown outwardp ing.

ly against the screen the same as from the spraying pans above. Of' course, it will be apparent that thev paintA which is raised or pumped up from the lower pan 29 will also carry some of the solid particles with it and these, as before, are thrown outwardly against the screen to drop down into the lower receiving pan 29. f

Thuswe not only have the spraying action of the upper pans, but the surplus Huid, and the fluid adhering to the solids, is 'successivav ly. thrown-or sprayed against the screen 21k until we have substantially a solid residue in the lower receiving pan 29, which when it becomes .filled mayv be removed for clean As previously pointedl out, if too much l paint is being fed to the machine, that is more than the screen 21 can take care oftheover flo-w pipe 34 will give indication thereof to lthe operator so that the amount being fed may be reduced.

The Huid or strained paint which has been separated from the solids and flows into the annular receiving pan 26, -continually lows therefrom through its outlet 27.

Thuswe have a continual rotary spraying separating action of the machine, whereby the solids are separated from the luid and such solid residue accumulated for removal.

To clean the various parts or secure access to the interior, the various elements may be removed from the machine or from their operative position and readily replaced.`

In the use of the machine it may be suspended from the ring 10 at the top of the machine and when the lower or receiving pan 29 is Vfilled it may be readily removed, cleaned and replaced. Or thev machine may be set on Vthe floor by letting it rest on the lower pan and then when this pan is filled the upper part of the machine, that is all the elements except the pan 29, lifted and either suspended oft' the floor or set over to one side by resting uponl the feet 28, which vas previously stated extend beneath the cone lse as to 4prevent damage thereto. n
